My AC clicks but the compressor does not turn on. What is wrong?

Clicking from the outdoor unit without the compressor starting usually means a worn contactor. The contactor is the relay that sends power to the compressor. When its contacts are pitted or worn, it clicks but cannot establish a solid electrical connection. Other symptoms: visible pitting or burn marks on the contactor face, AC works intermittently, or buzzing from the contactor.

Overview

This OEM 2-pole, 30-amp contactor with a 24V coil (part number 1178074) is the primary switching relay for the ICP / Heil / Tempstar RGS102HEBA0AAA unit. When the thermostat sends a 24V call, the coil pulls the contacts closed to deliver line voltage to the compressor and condenser fan motor. Pitted, welded, or chattering contacts are one of the most common causes of a system that won't start, won't shut off, or hums without engaging. A genuine OEM contactor restores clean, reliable switching at the rated 30A.

Is this contactor compatible with Bryant or Payne too?

Should I use OEM or aftermarket for my ICP contactor?

OEM recommended for reliability and warranty compatibility. OEM parts match exact factory specifications for proper fit, performance, and safety. While aftermarket alternatives cost less upfront, the risk of improper fit and reduced lifespan usually makes OEM the better value long-term.
